Step 1 :

\

General form of $\"\"$ is $\"\"$ .

\

The equatiotion $\"\"$ .

\

Rewrite the above equation.

\

$\"\"$ .

\

Use the formula : $\"\"$ .

\

$\"\"$

\

Add $\"\"$ on each side. \ \

\

$\"\"$

\

Take 4 as common factor from the right hand side of the expression.

\

$\"\"$

\

Divide each side by 4.

\

$\"\"$

\

Step : 2

\

To change the expression into a perfect square binomial add (half the $\"\"$ coefficient)² to each side of the equation.

\

Here $\"\"$ coefficient is $\"\"$ .

\

Find (half the x coefficient)² .

\

$\"\"$

\

(half the x coefficient)² is $\"\"$ .

\

\

Step : 3

\

Add $\"\"$ on each side.

\

$\"\"$

\

Rewrite the above equation.

\

$\"\"$ .

\

Use the formula : $\"\"$ .

\

$\"\"$

\

 \
Multiply each side by 4.

\

$\"\"$

\

Subtract $\"\"$ on each side.

\

$\"\"$

\

Rewrite above equation.

\

$\"\"$ .

\

Compare the above equation with the general form of $\"\"$ .

\

General form of $\"\"$ is $\"\"$ .

\
